PATENT LINE-SPACING. DEVICE.

SPECIFIC ATION forming part of Letters Patent No. 779,063, 'datedJanuary 3, 1905.

Application filed May 9i, 1904:. Serial No. 207,073.

To all whom t may concern:

Be it known that weWILHELM BENICKE and HEINRICH VVEs'rERBEcKfsubjects ofthe German Emperor, and residents of Hanover, Germany, have inventedcertain new and useful Improvements in Line-Spacing Devices, of whichthe following is a specification.

This invention relates to a device whereby the cylinder of atype-writing machine may be rotated round its axis for any requiredamount and that by closing an electric Contact.

vIn the annexed drawings, given by way of example, Figure I represents avertical section on Q R of Figs. III, IV, V,` Fig. II being a horizontalsection on S T of Figs. III, IV, V; Fig. III, a cross-sectiononU V ofFigs. I and II. Fig. IV is a cross-section on W X of Figs. I, II. Fig. Vis a cross-section on Y Z of Figs. I, II.

The cylinder proper comprises the hollow cylinder-body A, in which thesolenoid B is fixed. Inside the hollow cylinder-body A and at one end ofthe solenoid B are fixed the two guide-rails O C', while at the otherend of the solenoid B is placed the short hollow cylinder D, fixed tothe frame F by means oil a nut E. Upon the inner wall of the hollowcylinder D are arranged two helicoidal guides G G', Figs. I, II, III.The soft-iron core H, forming a part of the solenoid B and extended by abrass piece I, is guided by the crosspiece K, sliding upon the twoguide-pieces O (1. The free end oi' the brass pieceI carries the disk L,furnished with balls, which run in the egg-shaped grooves of the disk,Fig. IV. The guide-piece N, which is guided upon the helicoidal slides GG', is pressed by a nut vM against the balls of the disk L in such a waythat they can stillturn. One end of the winding on the solenoid B isconnected to the brush P, bearing upon the ring O, while the other endis electrically connected to the cylinder-body A.

If now by closing a contact an electric current is sent into thesolenoid B by the springbrush P and the ring O, the soft-iron core H isdrawn into the solenoid B, and consequently the guide-piece N alsoslides upon the guides Gr G'. Being arranged in a helix, the balls areis interrupted, the spring Q pushes back the core; but during thisperiod the roller A remains at rest. because the balls again run in thelargest part of the hollows. The angle to be rotated by the roller Aeach time the circuit is closed is regulated by the pin R, which ispushed into the hollow cylinder A and where it is rendered immovable bythe screw S. This pin limits the stroke or distance traversed by thesoft-iron core H and the piece I of brass.

Having now fully described our invention, whatwe claim, and desire tosecureby Letters Patent, is-

1. The combination with a hollow paper-receiving roller or cylinder of atype-writer, of a solenoid arranged therein, and having a slidable core,guide-ribs secured to the inner wall of the cylinder and parallel to theaxis of the latter and upon which guide-ribs the said core is slidablymounted at one end, a hollow cylinder fixedly arranged within thefirst-mentioned cylinder and provided with helicoidal guides on itsinner wall, a guide-piece adapted to travel upon the said helicoidalguides, coupling means interposed between said guidepieces and the coreand adapted to permit of the free revolution of the corewhen no electriccurrent is passing through the solenoid but to rigidly connect the coreand guidepiece when an electric current is passing through the solenoidand a spring arranged to act upon the core to return it to normalposition when no current is passing through the solenoid.

2. The combination with a hollow paper-receiving roller or cylinder of atype-writer, of a solenoid arranged therein, and having a slidable core,guide-ribs secured to the inner wall .of the cylinder and parallel tothe axis of the latter and upon which guide-ribs the said core isslidably mounted at one end, a hollow cylinder iixedly arranged withinthe first-mentioned cylinder and provided with helicoidal guides on itsinner wall, a guide-piece adapted to travel upon the said helicoidalguides, coupling means interposed between said guidepieces and the coreand adapted to permit of the free revolution of the core when noelectric current is passing through the solenoid but to rigidly connectthe core and guidepiece when an electric current is passing through thesolenoid, a spring arranged to act upon the core to return it to normalposition when no current is passing through the solenoid, and means forregulating the extent of movement of the core and consequently thedegree of rotation of the paper receiving roller.

3. Ihe combination with a hollow paper-receiving roller or cylinder oi'a type-writer, of a solenoid arranged therein, and having a slidablecore, guide-ribs secured to the inner wall of the cylinder and parallelto the axis ot' the latter and upon which guide-ribs the said core isslidably mounted at one end, a hollow cylinder {ixedly arranged withinthe first-mentioned cylinder and provided with helicoidal guides on itsinner wall, a guide-piece adapted to travel upon the said helicoidalguides, coupling means interposed between said guidepieces and the coreand adapted to permit of the free revolution of the core when noelectric current is passing through the solenoid but to rigidly connectthe core and guide-piece when an electric current is passing through thesolenoid, a spring arranged to act upon -the core to return it to normalposition when no current is passing through the solenoid, and a pinprojecting within the said paperreceiving roller and bearing upon oneend of the core, said pin being adjustable for the purpose specified.

4. The combination with a hollow paper-receiving roller or cylinder of atype-writer, of a solenoid arranged therein, a slidable core therefor,said core having a soft-iron section and a,brass section unitedtogether, guide-ribs secured to the inner wall of the cylinder andparallel to the axis of the latter and upon which guide-ribsthesoft-iron section of the core is slidingly mounted at its outer end,a hollow cylinder xedly. arranged within the first-mentioned cylinderand provided with helicoidal guides on the inner wall, a guidepieceadapted to travel upon said helicoidal guides, a ball-track in the outerend of the brass section of the core, balls interposed between saidbrass section and the said guidepiece and running in said track, and aspring acting upon the core to return it to normal position when anelectric current is not passing through the solenoid.

v In testimony whereof we have hereunto set our hands in presence of twowitnesses.
